4 5 place. The lever g can be depressed by hand As the shell containedin the tube F is carso as to release the carrier whenever it is deriedout of this tube to the first station, S, Fig. sirable. In thecircumference of the carrier 3, its rim acts upon a lever, n, which isfirmly are a series of semicircular recesses, 71, which mounted on avertical spindle, 0. This lever correspond in number and position to theacts on the powder-container J, so that the op- 5 number and position ofthe propelling-cavieration of the machine will cause the desired rooquantity of powder to be deposited in the shell when itis at thatstation. The shot is deposited into the shellin asimilar manner atanother station; but these do not form any part of my present invention.

As the shell is being carried from the first to the second station itsrim acts upon the lever O, which is mounted upon a vertical spindle, 0.This spindle has its bearing below in a socket in the platform B andabove in an arm, 1?, which extends from the hub I, Figs. 1 and 3. On thespindle 0, near its upper end, is firmly mounted a lever, 0 with acurved slot, 0 ,which engages with a pin, 0, Figs. 3 and 4. This pinprojects from a carriage, p, which moves in a radial slot in the armP,and which carries the wad-pusher 12 To facilitate the properadjustment of the levers O and 0", both of which are firmly secured tothe vertical spindle 0, this spindle is made in two sections, at and m,Fig. 9, which are connected to each other by a sleeve, m which carries aset-screw, ou By this means I am enabled to adjust the relative positionof the levers O and 0" with case, either when first assembling the partsor when they have been worn from use.

The wad-container Q consists of a series of vertical rods, or ofa tube,and it is provided with a gate, q, which can be adjusted so that thelowest wad in the wad-container can be pushed out by. the pusher 19. Asthe rim of the shell passes the lever O the pusher p is forced inward bythe slotted lever 0, and the lowest wad is carried over the shell, whereit is retained by two spring-jaws, 9 Fig. 2; The pusher p is immediatelydrawn back by the action of the rim of the shell upon the nose 0 of thelever 0, Fig. 3, whereby the spindle 0 is turned back to its normalposition. The shell has now reached station S, right beneath the wad,and the wad is driven down into the shell by the rammer R.

As it is desirable that the wad-container Q, which, as above described,may either consist of a tube or a series of vertical rods, shouldcontain as large a number of wads as possible, it is made of thegreatest possible length which the practical construction of the machinewill permit, and which is approximately indicated in Fig. 1 of thedrawings; but the length of the wad-container there shown will hold onlycomparatively few wadssay one hundredand would have to be refilledcontinuously by the operator. To obviate this constant filling by theoperator, I employ removable wad-feeding tubes K, Figs. 1 and 6, whichcontain a large number of wads. These tubes may be filled eitherdirectly at the wad-cutting machine or by a much cheaper grade of laborthan that employed to run my machines, permitting one operator to runthree cartridgeloading machines with ease, where one such machineformerly demanded his whole time. These wad-feedin g tubes may beperfect tubes with an opening at or near the lower end, or they may havea slit running their whole length, so as to permit the operatorto noticethe number of wads in the tube at any time and to remove the tubes whenthe wads therein have reached a point when it is necessary to insert afull feed-tube. To insure the downward passage of the wads in thesetubes, I employ a weight, 0, which will keep them in proper position andprevent the clogging of the tube.

By the subsequent movements of the carrier D the shell is movedsuccessively to the stations S S in each of which it receives an ad-.ditional wad. Then it is moved to the station 8*, in which it receivesthe shot, which'is introduced into the shell from the shot-container Jprecisely in the same manner in which the powder is introduced from thepowdercontainer J. After the shell has been charged with shot it ismoved by the carrier to the station S in which it receives a wad, andthen it is moved to station S in which it is crimped. This operationconsists in turning over the upper edge of the shell after it has beenloaded, as seen in Fig. 8, and is effected by means of the rotarycrimper T, the form of which is shown in Figs. 7 and S. This crimperconsists of a thimble, p, in the un der surface of which is formed anannular groove, q, the bottom of which is rounded. Into this thimble areinserted the crimpingpins 9, into each of which is cut a groove, 1).These pins extend into the annular groove q in such a way that while thegrooves p in the pins register with the annular groove {1 the bottom of'each groove 1) in the pin is situated in a different plane from thebottom of the annular groove in the thimble, thereby forming concaveprojections, Fig. 8, which act on the edge of the shell and turn thesame down, while the sides of this annular groove embrace the shell andprevent its distortion during the crimping operation. It is evident thatthe same result might be obtained by forming the concave projectionspdirectly on the bottom of the annular groove in the thimble. Thedifficulty of construction of such a form of crimper is obvious, whileby means of the crimpingpins the concave projections p can be producedwithout difficulty. These radial crimping pins are adj ustably fitted inthe thimble, so that they can be rotated axially in their seats for thepurpose of bringing new or fresh portions of their annular grooves intoposition for crimping when such grooves become worn in one place. Thepins are also readily removable, so that they can be replaced by newones, when desired, at small expense.

In the example shown in the drawings, Fig. 1, the crimper is secured toaspindle, t, which slides loosely through a bearing, t, in an arm, U,extending from the hub I, and also through the cross-head N, and isprovided with an adjustable collar, 1?. At its upper end is formed aconical teat, which fits a socket in the vertical shaft t", which has asliding bearing in the journal-box M, and which carries the pulley IIOit, connected by a belt with a countershaft, as shown in Fig. 1, fromwhich the required rotary motion is imparted to the shaft t and to thespindle t carrying the crimper T. In addition to a rotary motion, thecrimper must also have a rising and falling motion, so as to release theshell after it'has been crimped. This is accomplished by the cross-headN, to which a rising and falling motion is imparted from the main shaftE. In this cross-head is formed the bearing 15* for the spindle t, andin the example shown in the drawings, it consists of a bushing held inposition by a nut. When the crosshead is down, the crimper will rest onthe shell by the weight of the parts to which it is connected, in whichposition it will remain until it has performed its function, when itsfurther downward motion will be arrested by either or both of thecollars t i As the cross-head rises it will strike the collar t on thespindle t, and carry the spindle and the parts connected to it upwardand out of action until a new shell shall have come under the crimper,when it again descends, thereby permitting the crimper to act on saidnew shell. To prevent noise and to take h shock f h r s d against thecollar ii a Coiled sp g, lSplaced between these parts.

'1 am aware that a shell-crimper has been heretofore composed of acup-shaped bit having a circular groove in its base and provided withradial pins extended across said groove, slightly raised, and havinginclined grooves across their upper sides to assist in turning the edgesof the shells inward, Such, therefore, I do not claim.

Vhat I claim as new, and desire to secure by Letters Patent, is-

1. The combination, in a cartridge-loading machine, of the uprightcolumn A, the plat form B thereupon, the shell-carrier D, resting on theplatform, and means for intermittently rotating said carrier, with thevertical rotating shaft carrying a shell-crimper, T, at one end, and anautomatically rising and falling cross head, N, having a bearing, t",through which the crimper-carrying shaft passes, substantially asdescribed.

2. The combination, in a cartridge-loading machine, of the uprightcolumn A, the platform B thereupon, the shell-carrier D, the main shaftE, connections between the main shaft and the carrier for rotating thelatter, the vertical rotating shaft carrying a shell-crimper, T, and across-head, N, connected w th the crimper-carrying shaft and raised andlowered by the main shaft, substantially as described.
